1'0 all I D/7077b it may concern:

Be it known that I, PA'rnIoK MAGINNIs, residing at Kimball, in the county of Kimball and State of Nebraska, have invented certain useful Ilnprovement'sin Extensible Troughs; and I do herebydeclare that the followingis' a full, clear, and exact description of theinvention, such.as wil-henableothers skilled in the art to which it appertains-to make and us'e the Q same, re'ferenc'e wbein'gfh'ad .to the accompany- 1 ing drawings, which forni apart. of this specification.

This invention relates to a new and novel improvement in extensible troughs.

The object of my invention is to providea trough adapted'to be made the length of one unit or extended to comprise the combination of a pluralityof units to form a trough which may be readily taken apart and nested one unit upon the-other, so that the same, may be readily nested, crated, and shipped.

In the accompanying drawings I have shown in Figure 1 a side elevation of a trough embodying my invention comprising two units, with portions removed to disclose the structure. Fig. 2 shows atop view of the clamping-bar loss, while Fig. 3 shows a crosssectional view disclosing thejarrangement of the parts at the union of two elements or units.

My invention comprises a trough -shell, preferably made of sheetmet'aI, and which is nothing more or less than a rectangular. piece of sheet metal which has its upper ends flared outward, as is shown at b, to form a broad edge on top and atthesametirne give stability to the structure when assembled. These trough shells or section'sfare'preferably identical in length, and in' Fig. l' two such counterpart trough shells or sections Af and B have been shown. Each shellis provided near each end with an inwardly-extending rib, which upon the opposite side forms a groove into which the corresponding or complementary rib ofthe adjoining section fits, as is disclosedin l ig. 1 I The troughsections which are placed at the ends are closed and reinforcedby means of the end panels D D, preferably of wood, which panels are grooved, asj isshown at a, so as to receive the web a of the end trough-sections. These end sections D, which, as has been stated,

lsqnn. No. 70,956. (name-lei.)

.are preferably made of wood, are next pro- *vided with an iron bar 2 above, through which extend the U-shaped loop-bars O, having the ends threaded to receive the nuts 3,

so that at the ends' ea'ch trough-sectionis clamped and adjustably secured toan end "panel D by means of these U-shaped *loopgba'rs which ares'ec ired by meansof thenuts 3 The grooves a within'thetrough sections orshells formsea'ting's 'within'w'hichthe .U-

shaped loop-barsare'held, as isclarlyfshown Fig. 1, so that these bars cannot be displaced.

In securing two units or trough-sections, as

A. and B, in order to form an endless trough I'unite the ends of the trough=sectionsin placing the ribs one upon the other, but interposing between them a packing-strip 8,as is "shown in Fig. 1, and then placing upon the .top or inner trough-section a semicircular ribbed strip K, whichstrip K extends beyond the upper edge of the trough-section B, as is shown in Figs. 1 and 3. By virtue of the groove within this semicircular rim K this rim is not likely to be laterally displaced.

Transversely spanning the troughwherever two trough-sections arejunited is a spanner-'- bar 6, provided withthe downwardly-extending ears 7 7, which are adaptedto snuglywork against the upper rim f portions K to force them against the sides of the innermost trough-section, as is clearly shown in Fig. 3. This spanner-bar 6 has its ends perforated,

as is shown at 5 in'FigLB, and throughthese perforations passithe' threaded ends ofthe U-shaped loopbar G, which above is pro vided with suitable nuts,'as is shown in Fig.

- Now inorderto join two trough-sections it is simplynecessary to screw down the nuts 3, j which operation carries the U-shaped loops bar Oi'inward against the adjacent trough sections, while the spanner-bar 6 forces the rim K downward to tightly pinch and clamp the two trough-sections Aand 13 together, and this rinr being made of sheet metal cannot buckle inward, but insures a sn'ug'contact semicircular trough-sections can be used for the purposes of a washtub or like implement, such as feed-troughs or the like. A plurality V of these trough-sections united are nicely adapted to form flu mes. One of the end panels D may be provided with an opening m, as is shown in Fig. 3, into which a suitable plug may be driven, so that the trough may be emptied. When taken apart, they can be easily nested, so that they may be shipped in a knockdown condition. It is of course understood that these trough-sections may be made of various lengths and thicknesses and that the end panels D, which I have described as being made of wood, might also be made of iron or any other suitable material.

The device is noticeable because of its extreme simplicity, and,

Having thus described my said invention, what I claim as new, and desire to secure by United States Letters Patent, is

An extensible trough comprising a plurality of counterpart sheet-metal semicircular trough-sections, having their upper opposite edges bent at right angles and being provided at each end with an inwardly-extending rib forming upon the outsidea groove, in combination with two counterpart semicircular end panels provided with peripheral grooves adapted to receive the inwardly-extending ribs of aforementioned trough-sections, an upper strengthening-bar extending across and beyond each end panel, each bar being provided with end perforations, U -shape loopbars seating within aforementioned grooves exteriorly of each end tron gh-section, the upper ends of said loop-bars extending through said upper strengthening-bars and being secured by means of suitable nuts, a packingstrip interposed between the united ends of said trough-sections where they join one another, a semicircular grooved strip disposed interiorly above each point of union between two trough-sections to receive the aforementioned inwardly-extending rib of the uppermost trough-section, a transverse spanner-bar provided with downwardly-extending ears adapted to bear againstsaid semicircular rib at the upper ends, said spanner being provided with extending perforated ends and a U-shaped intermediate loop-bar Within the groove of the outer trough-section, passing through the perforated ends of said spanner and being suitably secured in the manner setforth.
